I readily be applied to bottles of; sizes and shapes. 4 1

Referring to the drawings forming part ofthis. pecifisz tio sl gar l. aisidei lev tion of the upper part of a bottle showing my cap in position thereon and closing it. Fig. 2 is a side sectional view of the same, showing the cap sufficiently opened to permit the bottle contents to be poured out, and ready to fly back when released. Fig. 3 is a side View of the same, showing the cap wide open. Fig. 4 is an approximately plan View of the cap. Fig. 5 is a plan View of the helical spring which controls the cap. Fig. 6 shows the cap used for removing a crown seal. Fig. 7 is a sectional view.

The great majority of bottles designed for the reception of tonics, beer and the like, are formed with a bead 1 about their mouths, and a shoulder 2 a short distance below such bead, such distance varying from an inch to five-eighths. The cap 3, which is preferably provided with a yielding disk 4 for render- I ing the closure more nearly air-tight, is formed with an extension 5 preferably integral therewith. In this extension is a laterally extended recess 6 designed to receive the sk nd er helical spring [whose ends are fas en d .teee e t m k a c rclela aw 5. HT-his circle is made small enough to; compel it. to elongate in order to reach around a bottleneck and through said rec'e'ss.

. i wings .9; of said; extension "are givenshoulders 10, which by rocking against the surface of the bottleneck, act; as a fulcrum to permit the capto be elevated from its seat OnthebOttlmouthby adownward pressure applied. to the terfrninal portion of extension, as shown in, Fig. 2 These shoulders are so positioned thatihe f an? of the helical spring against the, bottom 'ofsaid recess acitsto rock the cgapfba ck firmly to its olosed pos'itionf i i he extension 5has its sidewings formed with another pair'of shoulders lll so disposed that, by rocking the ca over m the wideopen position illustrated in Fig, 3 th e'fpiill oflthe helix will act to h olditlie mp, securely n; 11 P i P 'l h l Q'fi ei fi l b iii thus entirely unhindered; f by the pip, (the bottle can be readily refilled afterfwhicli a tap against the capf lw ill' pause t0 past, its; fulcrum a1id' ,.sn ap' back upon the mouth. f

i t is evident that the heliXse'rvesbT th to attach the ,t'olftl'ie bottle, and to'ifit' any .q m ivaaaaons.in. i meter pr its i'ai alsoto eonfinethecapupon the bottle mouth equall Well whe e t di tanc th gsh onlder 2 below the Bottle-mouth. I It further serves as the hinging member for the cap; the means for swinging the cap down upon the mouth, and also the means for holding the cap wide open.

For enabling the cap and its extension to be used forthe removal of sealing caps, such as the crown seal, from the bottles, said extension is formed with a wide slot 12 which is adapted to be engaged beneath the criinped edge of the crown seal, as shown in Fig. 6,

and by an upward pull upon the cap 3 to pry the crown seal off from the bottle.

Anothervery important use for this cap is for employment as salt and pepper. shakers. By'dispensing with the disk 4 and forming the cap with several small holes 13, as shown in Fig. 4:, the same can be applied to salt and pepper bottles, and used in the customary manner. The great advantage thereby given is that of a time saver in refilling the containers, inasmuch as the cap can be so readily thrown into its vertical wide-open position and filled without delay. This is especially desirable at summer hotels and large restaurants where time cannot be wasted in the laborious, and sometimes almost impossible effort, of unscrewing the screw-caps now in use for salt and pepper shakers.

What I claim as my invention is:

1. A closure for bottles and the like comprising a cap having a projection extending rigidly from the periphery thereof in a direction substantially at right angles to, the plane of the cap, and a resiliently extensible ring clasping the neck of the bottle for which said cap is designed and engaging said projection, the latter being formed with a shoulder resting against the bottle-neck slightly farther from the cap than is the point of said rings engagement therewith, to cause the pull of said resilient ring to press the cap down upon the bottle-mouth.

2. A closure for bottles and the like comprising a cap having an extension formed with a deep recess, and a helical spring formed into a ring resiliently clasping said extension in said recess and also the neck of the bottle used therewith.

3. A closure for bottles and the like comprising a cap having an extension, and a resiliently extensible ring engaging said extension and clasping the neck of the bottle used therewith, said extension having shoulders coacting with the surface of the bottle neck at successively different points.

4:. A closure for bottles and the like comprising a cap having a rigid projection formed with a shoulder the part of said projection between the shoulder and cap being substantially at right angles to the plane of the cap, and the remainder of the projection being angularly disposed, and a resiliently extensible ring engaging said projection and the neck of the bottle for which the same is designed, said shoulder and angularly disposed portion of the projection coming against the side of the bottle neck and coacting with said ring to support the cap in a wide open position.

5. A closure for bottles and the like comprising a cap having an extension, and a resiliently extensible ring engaging said extension and clasping the neck of the bottle used therewith, said extension being formed with a thumb piece and two pairs of shoulders coacting with the surface of the bottle neck, one pair of said shoulders permitting the pivotal return of the cap to the bottlemouth, and the other pair of shoulders serving, upon a lower depression of said thumbpiece, to holdthe cap wide open.

6. The combination with a bottle having a crown seal strongly closing it, the crown seal being formed with a crimped edge engaging the outer periphery of the bottlemouth, of a cap for temporarily closing the bottle after the crown seal has been removed, said cap being formed with a rigid projection extending radially from the cap, said projection having a transversely disposed slot adapted to be engaged with the crimped edge of said crown seal and the top surface of the latter for enabling the crown seal to be pried off from the bottle.

In testimony that I claim the foregoing invention, I have hereunto set my hand this 15th day of August, 1913.
